Is that new version freeware?  I think we ran into a for-pay version.

Took about a minute to load.  I did not manage to crash it but I have not 
yet figured out how to use it.  I can copy files over from the rest of the 
partition (from DOS) so I copied kermit.  No elm or mutt, no links.
No eznet.   I tried to load the sb sound modules but it said the device 
was already busy.  Won't play sound.  It has a lot of stuff for other 
hardware and locales and also all the compiler files and perl and loads of 
doc files and groff and all the man pages.

Is there some way to defragment the loop file or is this not necessary?
Mulinux had about 3000 linux files.  How many is a zillion?  Mulinux was 
about a 2MB download and this was a 37MB zip file so 20x3000=60,000 files? 
It may have been ten times that.  Too many for DOS to defragment.  Is 
there some limit as to how many files can be in a DOS partition?
